Example of mechanism to allow use of old VOB tags
For the UNIX VOB tag /vobs/special/code which must consist of two directories like your other VOB tags,
- create the new UNIX VOB tag /vobs/special_code
- create a new VOB tag /vobs/special which consists of the symbolic link /vobs/special/code => /vobs/special_code
- NT clients will use the VOB tag \special_code
